King Digital's stock price plunged more than 20 percent after a disappointing earnings report was released Tuesday. The company lowered its outlook for the rest of 2014 but said it still expects full-year growth from its gross bookings.

Analysts have voiced concern over the possibility that Candy Crush will be a one-hit wonder for King Digital, which depends on its most popular game for the majority of its revenue.

Arvind Bhatia, an analyst at Sterne Agee, told ABC News that King Digital needs to come up with another hit game to help put the company back on track.

"The challenge that King has is they have to replace all of this revenue with something else," Bhatia said. "But they're not able to replace the loss of revenue from Candy Crush, so they have a challenge."
